Question

所以我有点卡住了。我还在学习所有这些东西。但是我必须在我的应用程序中添加一个csv解析器，它应该在我的警报页面上显示结果。如果我做

return PartialView(model, pin, tDate, stat);

它会告诉我pin，tDate和stat在当前上下文中不存在。如果我将它们取出，应用程序将运行，但不会显示预期的结果。

我在UserADInfoModel.cs

中声明了pin，tDate和stat

这是控制器：

    public ActionResult _Alerts(UserADInfoModel model, List<string> groups)
    {
        DataRowCollection drColl = Core.GetAlerts(model);
        ViewBag.Alerts = drColl;

        var path = @"Exchange Migration data 10-25-17.csv";
        using (TextFieldParser csvParser = new TextFieldParser(path))
        {
            csvParser.CommentTokens = new string[] { "#" };
            csvParser.SetDelimiters(new string[] { "," });
            csvParser.HasFieldsEnclosedInQuotes = true;

            // Skip the row with the column names
            csvParser.ReadLine(); 

            // Read the lines
            while (!csvParser.EndOfData)
            {
                string[] fields = csvParser.ReadFields();
                string pin = fields[0];
                string tDate = fields[2];
                string stat = fields[6];
            }
        }

        return PartialView(model, pin, tDate, stat);
    }

这是视图

@if (@ViewBag.pin == Model.SAM)
    {
        <tr style="background-color : #ff3333; color: #ffffff">
            <td style="padding-left :10px; padding-right: 10px;padding-top:2px; padding-bottom: 2px">
                <p>Critical</p>
            </td>
            <td style="padding-left :10px; padding-right: 10px;padding-top:2px; padding-bottom: 2px">
                <p>Exchange Migration</p>
            </td>
            <td style="padding-left :10px; padding-right: 10px;padding-top:2px; padding-bottom: 2px">
                <p>Caller was set to migrate on (@ViewBag.tDate).  The status of the migration is (@ViewBag.stat). Please contact Hypercare</p>
            </td>
        </tr>
    }

    @foreach (var x in ViewBag.Alerts)
    {
        var uClass = (x["Weight"].Contains("Warning")) ? "#ff8c1a, " : (x["Weight"].Contains("Critical")) ? "#ff3333" : "";

        <tr @if (x["Weight"].Contains("Warning")) {
            @MvcHtmlString.Create("style=\"background-color: #ff8c1a\"")
        }
        else if(x["Weight"].Contains("Critical")){
            @MvcHtmlString.Create("style=\"background-color: #ff3333; color: #ffffff\"")

        }>

我做错了什么？ TIA

您在pin范围内声明了tDate，stat和while。

决定是否要使用模型（推荐）或ViewBag传递数据：

public ActionResult _Alerts(UserADInfoModel model, List<string> groups)
{
    DataRowCollection drColl = Core.GetAlerts(model);
    ViewBag.Alerts = drColl;

    var path = @"Exchange Migration data 10-25-17.csv";
    using (TextFieldParser csvParser = new TextFieldParser(path))
    {
        // ...

        while (!csvParser.EndOfData)
        {
            string[] fields = csvParser.ReadFields();
            model.pin = fields[0];
            model.tDate = fields[2];
            model.stat = fields[6];
        }
    }

    return PartialView(model);
}

_Alerts.cshtml：

@model UserADInfoModel
@if (@Model.pin == Model.SAM)
// ...
// ... @Model.tDate ... @Model.stat ...

PartialView（）;该名称在当前上下文中不存在
